Key to males of austral South American Mortoniella View in CoL
1 Ventral process of segment VI narrow basally, posteriorly directed; length usually 2 or more times width at base (if relatively short, then still distinctly narrow basally and posteriorly directed) ( Figs. 23E View FIGURE 23 , 27E View FIGURE 27 )................................. 2
— Ventral process of segment VI wider basally, length less than 2 times width at base (generally more or less subequal to width at base); process usually distinctly ventrally directed, subtriangular ( Fig. 5E View FIGURE 5 ) or short and rounded apically ( Fig. 15E View FIGURE 15 ), exceptionally somewhat posteriorly directed and length about 2 times width at base, but relatively wide basally and narrowed and subacute apically as in Fig. 22E View FIGURE 22 ( M. leroda species group and unplaced species) ( M. armata , couplet 4, placed here presumptively) .................................................................................................... 4
2(1) Size larger (forewing usually more than 4 mm.); hind wing with forks II, III and V present ( Fig. 39B View FIGURES 38–40 ) ( M. bilineata species group and unplaced species M. argentinica )............................................................... 34
— Size smaller (forewing usually less than 3 mm.); hind wing with fork II only ( Fig. 40B View FIGURES 38–40 )............................. 3
3(2) Rod-like appendages of phallotheca short and accompanying pockets not conspicuously enlarged ( Fig. 26A View FIGURE 26 ) ( M. ormina group)............................................................................................. 29
— Rod-like appendages of phallotheca elongate and inflated apically, accompanying pockets very bulbously enlarged ( Fig. 27A View FIGURE 27 ) ( M. velasquezi group)................................................................................. 32
Mortoniella leroda group (and unplaced species)
4(1) Dorsal phallic spine trifurcate apically ( Jacquemart 1963, fig. 7)............................ M. armata (Jaquemart) .
— Dorsal phallic spine simple, undivided, not trifurcate apically ( Fig. 1A View FIGURE 1 ).......................................... 5
5(4) Segment IX with anterior margin more or less evenly rounded in lateral view ( Fig. 1A View FIGURE 1 ) ( M. leroda group)............... 7
— Segment IX with anterior margin either distinctly produced in ventral 1/2 ( Fig. 36A View FIGURE 36 ), or nearly straight ( Fig. 37A View FIGURE 37 ) (unplaced species)............................................................................................. 6
6(5) Segment IX with anterior margin distinctly produced in ventral 1/2 ( Fig. 36A View FIGURE 36 )..................... M. guairica (Flint) .
— Segment IX with anterior margin nearly straight ( Fig. 37A View FIGURE 37 )....................................... M. meloi , n. sp.
7(5) Phallic ensemble (apparently) with 2 pairs of elongate lateral appendages (1 pair of paramere appendages and 1 pair of appendages emerging from dorsolateral margin of phallicata, Figs. 19A, 19C View FIGURE 19 , 22A, 22C View FIGURE 22 ); endophallic membrane without ventromesal spine ( Figs. 19A View FIGURE 19 , 22A View FIGURE 22 )................................................................................. 8
— Phallic ensemble with only 1 pair of lateral (paramere) appendages; endophallic membrane with distinct, sclerotized ventromesal spine ( Fig. 1A View FIGURE 1 ) [absent only in M. truncata , n.sp.]......................................................... 9
8(7) Tergum X with apicomesal margin convexly rounded, not notched ( Fig. 22B View FIGURE 22 ); apex of dorsal phallic spine weakly notched (bifid) in dorsal view ( Fig. 22C View FIGURE 22 ) ( M. punensis subgroup)...................................... M. punensis (Flint) .
— Tergum X with apicomesal margin incised ( Fig. 19B View FIGURE 19 ); dorsal phallic spine, in lateral view, with enlarged rounded protrusion at inflection point ( Fig. 19A View FIGURE 19 ) ( M. pocita subgroup)............................................... M. pocita (Flint) .
9(7) Inferior appendages short, without distinct, upright dorsolateral projections ( Fig. 20A View FIGURE 20 ); dorsal phallic spine very inflated in middle (lateral view) ( Fig. 20A View FIGURE 20 ); tergum X shallowly notched apicomesally ( Figs. 20B View FIGURE 20 , 21B View FIGURE 21 ) ( M. pumila subgroup)...... 10
— Inferior appendages with very apparent upright dorsolateral projections ( Fig. 1A View FIGURE 1 ); dorsal phallic spine usually either not or much less inflated in middle (lateral view) ( Fig 1A View FIGURE 1 ); tergum X more deeply incised apicomesally ( Figs. 1B View FIGURE 1 , 17B View FIGURE 17 ) ( M. albolineata subgroup)....................................................................................... 11
10(9) Paramere appendages elongate, as long as or longer than dorsal phallic spine ( Fig. 20A View FIGURE 20 ); tergum X with apicomesal margin very weakly notched ( Fig. 20B View FIGURE 20 ); apicolateral seta of tergum X not on finger-like process ( Figs. 20A, B View FIGURE 20 )... M. pumila , n. sp.
— Paramere appendages short, distinctly shorter than dorsal phallic spine ( Fig. 21A View FIGURE 21 ); tergum X with apicomesal margin more distinctly notched ( Fig. 21B View FIGURE 21 ); apicolateral seta of tergum X on distinct finger-like process ( Figs. 21A, B View FIGURE 21 ).... M. pusilla , n. sp.
